DTITSIDE BRAKE.

ssoa'ia.

Application filed August S To all whom it may concern Be it known that I. CLirToN VAN Co'r'r, a citizen oi the United States, and a resident of Cold Spring Harbor, county oi Suliiolk, and State of New York, have invented a new and Improved lutside Brake, of which the following is a full, clear, and exact description.

This invention relates to improvements in. outside brakes and more particularly to an outside brake structure which can be ap plied to the hrakedrum of a well known type of a utomenile on the market which has heretofore been equipped with an. inside brake structure.

To be more specific, a. well known type of automobile on the market has heretofore been provided. with brake band located inside the drum, and is the purpose of my invention to provide a structure which can be utilized on the outside of the some drum to take the place of the inside brake structure, and by this change I provide a brake which is readily accessible, which is not liable to get out of repair, but it it does, can be easily attended to.

A further object is to provide hrahic which. insures the uniform mi'weinent of the bra-lie band in all directions toward or away from the brake drum so as to permit a quick acting; .eii'ccl'ual brake and a quick releasing hrahe band without danger of wear band when the latter is not applied. these and other objects in view, the .on co. sists in certain novel features of co. .ruc .on and combinations and an rangenients of parts will be more fully hereinafter described and pointed out in the claim.

in the accompanying drawings:

Figure 1 is a view in, side elevation partly in section illustrating my improvements.

Fig. 2 is a top plan view of 1 with part shown in section.

Fig. 3 is a view similar to Fig. 1 but oi the opposite side of the brake, the drum being removed for clearnes.

Fig. 4 is a View in front elevation oartly in section.

Fig. 5 is a fragmentary view of one end of the brake hand and attached part.

1 represents the axle and 2 the wheel of a type of automobile in common use, dish 3 being employed and fixed to the axle casing 4. The disk is strengthened by brace 5 which, at Its forked rear end, is secured Specification of Letters Patent.

by bolts 6 and nuts 6. 7 represents a crank arm which was utilized to operate the internal brake and all of the structure above described is in couunon use on a well known type of automobile and is utilized with the exception of the crank arm 7 in connection with my improved outside brake, so that my improvements may he attached without changing; the well known structure. It is of course understood that before my improvements are attached, the internal bi: kc mechanism removed and the rod 33, which "as used to operate the crank arm 7 can be utilized to operate my improved brake as will hereinafter appear.

b represents the brake drum which I utilice, applying my 1 nice to the outside'in stead oi to the inside as heretofore.

The brake band 5 may he of any suitable I form and given a friction surface in any desired way, and positioned around the outside of the drum 8. i bracket 10 is fixed to the disk 3 and connected by links 11 with the soriug 12 of the lever.

bracket arm 13 is secured at its intermediate portion on one of tie bolts 6, and at its rear end is secured bybolt 14, these bolts 6 and i l being secured in the stationary disk 3. An extension 15 is provided on the rear end of bracket arm 13, and has a block 16 integral therewith projecting laterally from the bracket arm 13 and positioned in socket frame 17, the latter secured to the intermediate portion of the brake band -9. A. threaded bolt 18 is fixed to the block 16, projects at'right angles therefrom, and is movable through the outer end of the frame 1?. Nuts 19 are screwed on to the outer end of the bolt 18 and a coiled spring 20 is 10- cetedarouncl the bolt between the block 16 and the outer end of the frame 17, exerting pressure on the frame tending to draw the intermediate portion of the brake band 53 away from the brake drum.

The bracket 13. at its forward end is made with an upwardly. curved. portion 21., the latter having laterally projecting perforated his; 22 receiving vertical rod 28 therein. upper end of the rod 23 projects through a perforated lug 2 on one end of the brake band 9, and nuts are screwed on to the upper end of the rod and. against the log 24:. The lower end of the rod 23 has a pivotal connection with an operating lever 34. This pivotal connection 26 is slightly in advance of the pivotal con- -31 on the rod 23.

nection 27 between the lower rear end of the lever 34, and 9. lug 28 on the other end of the brake band. A coiled spring 29 is located around the rod 23 between the perporated lugs 22 and 24. A. second coiled spring 30 is located around the rod 23 between the perforated lug 22 and a shoulder These springs tend to force the ends of the brake band apart, while the spring 20 above referred to moves the intermediate portion of the brake band away from the brake drum, so that when the brake band is released its entire inner sur* face is moved away from the drum.

The operating lever 34 above referred to not only curves upwardly and then rearwardly as shown in Fig. 1, but also projects laterally as shown clearly in Figs. 2 and e, and is provided with an operating rod having, a pivotal connection with the upper end of the lever 34.

The operation is as follows:

lVhen the rod 33 is moved to the left 01 Fig. 1, the lever 34: will be swung forwardly and downwardly, causing the lever to tulcrum on the pivotal connection 26 as well as on the pivotal connection 27, so that through the medium of the rod 23, the upper lug 24 will be pulled downwardly, and through the medium of the lugs 24% and 27, the brake band will be drawn tightly around the drum 8 and the desired braking action can be had. When. the pull on the rod 33 is released, the springs 29, 30 and 20 will draw the brake band away from the brake drum and hold the brake band in this position until it is again applied.

Various slight changes might be made in nee s-1e the general form and arranging of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

Having thus described my invention, what I c'iaim as new and desire to secure by Letters latent is:

The combination with. a stationary disk, a rotary drum and a brake band around the drum, of a bracket arm fixed to the disk, an extension on the rear end of the bracket arm, a laterally projecting block on the extension. integral with said bracket arm, a socket frame on the intermediate portion of the brake band, into which the said block projects, a bolt on the block extending through the, outer end of the socket frame, a nut on the outer end of the bolt, a coiled spring around the bolt, between the block and the outer end of the frame tending to move the intermediate portion of the brake band away from the drum, an operating lever pivotally connected to one end of the brake band, a rod pivotally connected to the lever, a perforated lug on the other end of the brake band receiving the rod, a perforated lug on the bracket arm through which the rod projects, coiled springs around the rod. above and below said last mentioned lug, holding the rod in place, one of said springs exerting pressure on one end of the brake band and the other of said springs exerting pressure on the rod.
